MAF problem??? Help
My son drives my 94 ranger 4.o 4x4.
Yesterday he turned the key, and before it started completely, he let go of the key and a noise and Poof of smoke came out under the hood. ( I guess it back fired?!?!). It did start up, and he drove it home, but it is idleing low, and stalls at idle. When I disconnect the MAF sensor, it idles fine, but the Check engine light flashes.
I took the MAF sensor off and cleaned it with MAF Cleaner, and it ran OK when warm, but when I started it this morning, It wouldn't idle..... Keeps stallilng. Do I need to replace the MAF??? What else could this be??
All help and comments are welcome.

Thanks for your replies..... after work, while it was still light.... I took
another look.
Seems the backfire blew off a vac hose on the vac tee at the back of the motor.
Connected the hose and all is well.
thanks guys
